Rust blueprint serialization issue

[niroam]

With the rust code, when building a policy the add_method uses this code to serialize the Method enum

serde_json::to_string(&method).unwrap()

this creates a policy with double quotes in the method ARN
"arn:aws:execute-api:ap-southeast-2:XXXXXXXXXX:YYYYYYYYYY/ESTestInvoke-stage/\"*\"/*"

Consider using something like this instead ?

json!(&method).as_str().unwrap()
